To all whom 'it may concern:

Be it known that I, JOHN A. WESER, a citizen of the United States,residing in the borough of Manhattan of the city of New York, in theState of New York, have invented certain new and useful'lmprovements inGraphophones, of which the following is a specification, reference beinghad to the accompanying drawings, which form a part hereof.

It has'been proposed to control the operations of a graphophone by meansacting automatically and in proper sequence whereby the proper startingand stopping thereof is effected and different records successivelyplaced in operative position. Such means have usually been mechanicallyconnected to the actuating mechanism of the disk turn table and once thedevice was set in motion various controlling devices had to performtheir respective functions before a different record could be placed inposition and the parts reset. Further, in these prior devices, it wasnot possible to repeat a portion of the composition on the particularrecord in operative position. The transfer of records in sucharrangements has usually been effected by the bodily movement ofsuitable 'frame supports therefor and the means to effect the movementof the frames when desiredk have necessarily been too complicated anddelicate for general use and didnot admit of the application of thedevices to any graphophone. Further, the cont-rol mechanisms have neverbeen so related to each other and to a common source of power that thosemovements which should properly be cordinated and yet independent ofother sequential control movements, could be initiated independently.Neither has any 'arrangement been provided to permit the operations of agraphophone to be controlled froma distance by an attendant.

Accordingly, it is an object of this invention to overcome thedisadvantages hitherto encountered in automatically controlledgraphophones and to provide a machine which shall be of comparativelysimple construction, substantial in its nature, of relatively few movingparts, inexpensive to manufacture, invariable in its operation,susceptible of control at all stages of its operation and ata distanceand generally of a character which shall commend" itself to users of allclasses.

any desired place, the sound box together with the needle may be loweredtooperative position in engagement with the disk whereupon thecomposition thereof will be rendered. When desired, other pneumaticallycontrolled devices may be set in motion to lift the needle from therecord and permit the sound box to be returned to a predeterminedstarting position; the rotation of the turn table stopped; the uppermostrecord removed from its position on the turn table thus bringing therecord immediately thereunder into operative position; the turn tablereleased to permit its further rotation; and the sound box and needlelowered to engage operatively the uppermost record, after which theoperations above outlined are repeated or modied at the will of the operator until the lowermost record has been removed from the turn table.

In the embodiment herein illustrated the several control devices areactuated pneumatically, a switch being provided at any desired placebetween the source of power' and the several independent pneumaticcontrolling devices, whereby the latter are set in operation at will.

Further improvements will appear as this description proceeds, amongwhich may here be mentioned the means for controlling the volume ofsound to regulate theexpression, f

means to insure automatically the return of the sound box to any desiredpredetermined position with respect to the record and a multiple needleholding device for the sound box.

The invention will be more fully described with reference to theaccompanying drawings, in which- Figure 1 is a view in plan of-a'graphophone embodying the present invention and showing certain ofthe pneumatic control-A ling devices, the latter being in the normalposition immediately prior tothe rotation of the turntable.

In the following description the variousl parts entering into theconstruction `of van improvedgraphophone embodying the present inventionwill be described with referand the Several groups ofi-elated'pneuniatic controlling devices.

For the. purpose of this description a graphophoiie of ordinaryconstruction is Fig. y

herein ,illustrated1 being composed of the usual operating partsdisposedsubstantially iii their ordinary relationship each to each andperforming their respective well known functions. y

As the description proceeds it will be evident that the invention isapplicable to any Igraphophone of the disk-record type. The graphoplioneproper may be disposed within a suitable cabinet a having a horizontalpartition a therein for the support of the kusual operating devices andbeneath which may be disposed the actuating motor (omitted herein forthe sake of clcarness) for the turn table b,-the latter having a post bcoincident with VitsvtaXis and adapted to eX- tend through theusualcentral apertures c of the disk records c which are supported by thetable. 0n the horizontal partition a is also mounted the usual d havinga swivel connection with its base CZ to permit its free movement in ahorizontal plane and having swiveled thereto the usual goose-neck piped2 in connection with the sound box d, all as in a manner well known.One end of the horizontal partition a terminates adjacent a downwardlyextending flat support a2 which may be provided with side walls ai andlined with a resilient covering at, for a purpose which will laterappear herein. It should be noted here that while the relationship ofthe parts thus far described may be changed at will, it is necessarythat the inclined open receptacle last described, comprising the flooro? and side walls fr, lie in juxtaposition to the turn table so as toreceive the records therefrom, from time to time during the operation ofthe graphophone. j

A feature of the invention hereinbefore referred to and which mightproperly be de.- scribed at this point resides in the provision ofsuitable buffers designed to limit the movement of the sound horn in onedirection so that the sound box may be stopped iio ment two such buffersare described, one, as i illustrated in detail in Fig. 8, being designedprimarily for the` repeat of :in entire record disk, and the,` other,shown best in Fig, 1, being intended primarily for thc repeat fofportions only of the composi' tion of the record. The first namedbutler, herein designated generally by the reference character e, ismounted rigidly on the horizontal partition a and includes a horizontaltubular portion e in whichI is disposed :i spring pressed plunger .c2having a suitable handle c3 at one end adapted to be grasped by theoperator` and a suitable resilient cushion eL at the other end withwhich the tone arm d contacts as will presently appear. The tubularportion c has threaded therein a set screw ci by which the position ofthe rac ing now to the fingers Z and Z briey referred to above, it willbe seen that the uppermost Vfinger Z is pivotallymounted on the finger Zon a stud Zi and moves upwardly with respectto the lower finger Zagainst the action of a suitable leaf spring Z5 operatively interposedbetween the two fingers. The normal relationship of these fingers may befixed by means of an adjusting screw Z6 threaded in one finger Z andengaging the other' finger Z. i

The upper finger Z rests at all times on the upper face of the uppermostrecord, while the lower finger Z is adjusted with respect to the upperfinger by means of the stud Z6, so that the lower finger has its outeredgesubstantially in the same plane with the under face of said record.When it is desired to remove the uppermost record c the bellows n iscollapsed, rotating the vertical shaf't m and swinging the support m,arm Z2 and fingers Z and Z inwardly radially with respect to the record.The cam surface of the finger Z is so formed that the initial movementof the disk record thereon. is upwardly against the action of the uppernger Z and its spring Z5. This upward movement ofl the diskserves tobring its aperture c out of engagement with the vertical post b of thetable b so that by continued inward movement of the fingers, the recordis slid bodily toward the inclined support a2. As appears from Figs. 1.and 2, when the record is slid outwardly to a point where it isoverbalanced,'it falls on said incline and is guided in its movement toa position of rest by the side walls a3 thereof. By suitablemanipulation of the controlling valve, hereinafter described, the

bellows n may now be allowed to collapse so as to swing the arm Z2 andthe intermediate connections back to their normal position in which theupper finger Z rests on the disk immediately below the one removed.

The other parts before described may then be set in motion to render thecomposition of the uppermost record.

lt may be desirable at times to control the volume of sound inaccordance with the nature of the selection and so the cabinet a, ishere illustrated as provided with a shutter a" hinged in one of itsside/walls. This Ishutter a is connected through suitable links n? to a.'bellows o suitably secured within the cabinet. In the embodimentillustrated, when the bellows o is collapsed the shutter fr. is closedand for all intermediate positions of the bellows o when being distendedthe shutter is opened a corresponding eX- tent.

From the description thus far given, it is thought that the desirabilityof employing a multiple needle l, holder to permit a fresh needle to bebrought into place quickly, will now be appreciated. One form of such aneedle holder is illustratedin Figs. 16 and 17. This comprises anannular carrier p provided with a plurality of recesses p in one end toreceive the needles, which may be secured therein by suitable set screwsp2 and having the other end in operative connection with the sound boXd3 in the ordinary manner. In use, any one of the needles may be broughtinto operative position quickly with respect to the record by rotatingthe support p, as will be obvious.

A. slightly modified form of avmultiple needle carrier is shown in Figs.18 and 19. This comprises a suitable yoke g carried by the sound boX Z3and having journaled in its branches a holder g', in the periphery ofwhich may be disposed a plurality of needles. The annular holder g isformed with two relatively movable portions between which are disposedthe needles. These portions may be moved relatively by means of asuitable milled nut q2 in a. manner which will be obvious to a skilledmechanic and which need not here be illustrated in detail.

The parts constituting the Aimproved graphophone and controlling devicestherefor having now been described with sufficient detail, the controlsystem for these several devices will now be considered. In thisconnection reference is to be had particularly to the diagrammatic viewof Fig. 3. In this figure, in the interest of clearness, the sound boxand sound horn together with their controlling bellows have been shownin side elevation, while the break bellows, the record shiftingmechanism and the expression shutter have been shown in plan. The masterbellows is in the present embodiment adapted to be operatedmanually, butit is to be understood that any master bellows controlled by mechanicalor pneumatic devices may be substituted. lSuch an arrangement wouldbeespecially desi 1able when the improved graphophone is use in connectionwith a pneumaticpiano player or the like.

The master bellows r has connection, through suitable piping -r and r2with a controlling valve or switch which may comprise a member a,secured for the sake of convenience on a table t or the like and havingpivotally secured thereto a valve member s on which is pivotally secureda second valve member s2. rl`he location of the switch with respect tothe graphophone and to the master bellows may be changed as desired. Asshown particularly in Figs. 13, 14 and 15, the master bellows connectionr terminates in a port s3 extending through the valve member a2 andadapted to be placed in registry with a second port s4 formed in theadjacent valve member s. The other connection 'f2 from the masterbellows r terminates in a port s? formed in the valve member s, whichmay be placed in registry with any plunger e2 with respect to the soundhorn d may be adjusted so that the movement ot the latter is stopped inone direction 1nvariably at a. predetermined point. When it is desiredto repeat a portion only of a record theother butler device f ispreferably employed. This last named butter comprises a vertical stud fcarried rotatably by the horizontal partition a and having threadedtherethrough a plurality of horizontally disposed butler studs gcarrying suitable cushions g at one end to contact with the tone arm din a manner lsimilar to that pointed out with respect to the butter e.By employing the buli'er device j as many predetermined repeat positionsfor the sound horn may be secured as there are horizontal threaded studsg and so, by rotating the butter device to bring the proper cushionedstud in operative position for successive records. the favorite portionsot each record may be repeated without interrupting the renditionthereof to adjust the stop. lVhile it has been stated that the bufferdevices c and j above described have especial application to therepeat/of records under cer-- tain conditions it is to be understoodthat either may be used as repeat stops under all circumstances.-

The sound box d3 with its needle may be lowered or raised from operativeposition by means of an arm it which preferably eX` tends through thegoose-neck pipe (Z2 and has one end lying thereunder so that when thislast named end is raised the sound box will be'raised .in a mannersimilar to that employed when the box is raised manually by theinsertion ot a finger under the gooseneck pipe. The other end of thelever z. is secured to the movable member h of a bellows h2 carried by asuitable bracket (l secured on the sound horn Z and movable therewith.This bellows il? is normally held in distended position by a spring h3as is usual in such devices. When the bellows lz? is in its distendedposition as is illustrated in Fig. Il, the sound box d3 and its needlerest by gravity in operative position on the tace ot the uppermost dishrecord c. When it is desired to raise the sound box d and its needleJrom this position the bellows It* is collapsed. thus swinging upwardlythe outer end of the lever It together with the goose-neck pipe (Z2which rests thereon. When the needle -is released from its en'- gagementwith ner just pointed out, the tone arm fZ is brought under the actionof a suitable spring` (Z5 which serves to move the same toward vitsinitial position. ,als pointed out before. however, this Swingingmovement or" the tone arm al may be stopped either in its inwardstarting position. as or at any predetermined repeat"` point` as bymeans of the butter f.

` sition by the record disk in the n'ianb v the butler e,

To stop the rotation of the turn table D or to permit its rotation, asuitable brake i is provided by two bellowsj and la, lying injuxtaposition to each other and supported. on the horizontal partitiona. The Inovable member jof the bellows j may carry the brake t', and itsmovable member is so disposed with respect to the periphery ot the turntable as to bring the brake in engagement therewith when the bellows isin its distended position. rl`he bellows j and c are normally held intheir distended posprings jg and 7c respectively`v as will beunderstood. To permit the turn table b to rotate under the action of itsmotor, the bellows y' is collapsed, thus withdrawin the brake i fromengagement with the periphery of the table. Vllhe bellows j is held inthis collapsed position by the. engagement of a suitable lent spring isearried on the movable member j which has a slot adapted to engagereleasably a stud j" mounted on the immovable member of the bellows, asappears most clearly in Figs, ll and 12. lVhen it is desired to startthe rotation of the turn table b the bellows 7.: is collapsed so thatits movable member 7a2 which carries aV stud 7c3 in its end, will bringthe stud its in operative engagement with the leaf spring ja so as todisengage the latter from the stud y" and permit the bel lows y' tobecome distended so that the bra he @l is brought into Contact with theperiphery of the turn table b.

After the composition et the uppermost record c has been rendered andperhapsaepeated wholly or partially at the will of the operator, itv isproposed in accordance with the present invention to have the sameremoved by suitable means also under the control of the operator so asto bringl the dislr immediately thereunder in operative position withrospo-1st to the sound box d and its needle. llllhen this is broughtabout,

' bed may be re the movements before der, peated with respect lo the newdislt. 'The mechanism for removing the uppermost revord comprises a camlinger Z which is adapt-- ed to be slid under the record and a primapressed cani finger Z carried thereby and reversely disposed withinspect thereto to engage the upper 'face oi' the record. The finger Zis adjustably 'secured to one end of an arm Z2 by means of a set screwZi'. The journaled loosely other end ot the arm in a suitable support m.secured to a vertical shaft m' rotatably mounted in a bracket u"carried by the cabinet a (see Fig. 9j). 'l`he shaft 'nt' in turn. isoperatively connected to a bellows fn/ also secured to the cabinet a,through suitable links m,2 and mf". The angular relation of the supportm, to the shaft m as well as the angular relation ot the linlr m2thereto. may be lined by suitable set screws m4 and mf' respectively.

in the bellows h2 is a pipe connection u, by

which the bellows h2 may be collapsed as will later appear. leadingtherefrom a branch connection u which terminates in an immovable valvemember h5 carried by the bellows h2. This valve member h5 has a port 71,with which is adapted to register a port zf formed in a movable memberlas pivotally secured to the immovable valve member h5. The movablevalve member its is normally held so that its port k7 is out of registrywith theport Itv of the immovable valvemember it by means of a suitableleaf spring h".
